Royal Purple Synchromax Manual Transmission Fluid

Unrivaled Protection. Royal Purple Synchromax® is a full synthetic transmission fluid that provides superior wear protection for your Bronco's drivetrain. Synchromax® is formulated with Royal Purple's synthetic, proprietary Synerlec® additive technology, which offers improved shift quality over a wide temperature range and reduced gear noise. Use Royal Purple Synchromax on your Bronco's next fluid change for the cheapest insurance you can get against future transmission breakdowns.

Smoother Shifts. If your transmission is notchy, rough, or loud but is mechanically fine, a fresh fill of Synchromax® can help smooth things back out. If you have a new Bronco or transmission, changing your fluid to Synchromax can keep your transmission working better - both now and later.

Protects Internal Components. Synchromax® is fully compatible with all types of friction materials and offers excellent corrosion and oxidation protection without affecting the soft metals commonly found in manual transmission synchronizers.

Application. Synchromax® is recommended for manual transmissions on 2021-2024 Bronco that specify an automatic transmission fluid or motor oil and is also suitable for transfer case use.
